## API Overview

### Core Classes

#### GraphDB
```javascript
const db = new GraphDB('cosine');
db.createNode(labels, properties)
db.createEdge(from, to, type, properties)
db.createHyperedge(nodes, description, embedding?, confidence?)
await db.query(cypherQuery)
db.stats()
```

#### JsNode
```javascript
node.id
node.labels
node.properties
node.getProperty(key)
node.hasLabel(label)
```

#### JsEdge
```javascript
edge.id
edge.from
edge.to
edge.type
edge.properties
```

#### JsHyperedge
```javascript
hyperedge.id
hyperedge.nodes
hyperedge.description
hyperedge.embedding
hyperedge.confidence
hyperedge.order
```

### Advanced Features

#### Async Query Execution
```javascript
const executor = new AsyncQueryExecutor(100);
await executor.executeStreaming(query);
```

#### Transactions
```javascript
const tx = new AsyncTransaction();
tx.addOperation('CREATE (n:Person {name: "Alice"})');
await tx.commit();
```

#### Batch Operations
```javascript
const batch = new BatchOperations(1000);
await batch.executeBatch(statements);
```

## Building

### Prerequisites

1. Install Rust toolchain:
```bash
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
```

2. Install wasm-pack:
```bash
curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh
```

3. Add WASM target:
```bash
rustup target add wasm32-unknown-unknown
```

### Build Commands

#### Build for Web (default)
```bash
cd /home/user/ruvector/crates/ruvector-graph-wasm
./build.sh
```

Or using npm:
```bash
cd /home/user/ruvector/npm/packages/graph-wasm
npm run build
```

#### Build for Node.js
```bash
npm run build:node
```

#### Build for Bundlers
```bash
npm run build:bundler
```

#### Build All Targets
```bash
npm run build:all
```

### Using in Projects

#### Browser (ES Modules)
```html
<script type="module">
import init, { GraphDB } from './ruvector_graph_wasm.js';

await init();
const db = new GraphDB('cosine');
// Use the database...
</script>
```

#### Node.js
```javascript
const { GraphDB } = require('@ruvector/graph-wasm/node');
const db = new GraphDB('cosine');
```

#### Bundlers (Webpack, Vite, etc.)
```javascript
import { GraphDB } from '@ruvector/graph-wasm';
const db = new GraphDB('cosine');
```

## Integration with RuVector

This WASM binding leverages RuVector's hypergraph implementation from `ruvector-core`:

- **HypergraphIndex**: Bipartite graph storage for n-ary relationships
- **Hyperedge**: Multi-entity relationships with embeddings
- **TemporalHyperedge**: Time-aware relationships
- **CausalMemory**: Causal relationship tracking
- **Distance Metrics**: Cosine, Euclidean, DotProduct, Manhattan
